Urban Growth Stage of Seoul Metropolitan Region by Residential Mobility Network

Abstract

The differential urbanization model is a theory that analyzes urban growth stage based on residential mobility between cities, and it is possible to examine the linkage structure between primate cities, intermediate cities, and small cities. Therefore, this study analyzes the urban growth stage of the Seoul Metropolitan Region(SMR) from 2001 to 2020 and the change of residential mobility network for each growth stage based on a differential urbanization model. The results are as follows. First, the urban growth stage of the SMR is analyzed Advanced Intermediate City Stage in 2001-2006, Early Small City Stage in 2007-2016 and Advanced Small City Stage in 2017-2020. Second, as with the theory, it is analyzed that the spatial dispersion into small cities has expanded further over the past 20 years in SMR. Third, it is analyzed that the network with Seoul and SMR has weakened over the past 20 years, and the network between small and intermediate cities in SMR has increased. This study can be used as basic data for future planning of SMR.
